In the work of Maeterlinck and Claudel on the one hand, and those of M. Bergson on the other, we have the mixture of the genres in which our age delights. Every work of imagination must have a philosophy; and every philosophy must be a work of art—how often have we heard that M. Bergson is an artist! It is a boast of his disciples. It is what the word “art” means to them that is the disputable point. Certain works of philosophy can be called works of art: much of Aristotle and Plato, Spinoza, parts of Hume, Mr. Bradley’s _Principles of Logic_, Mr. Russell’s essay on “Denoting”: clear and beautifully formed thought. But this is not what the admirers of Bergson, Claudel, or Maeterlinck (the philosophy of the latter is a little out of date) mean. They mean precisely what is not clear, but what is an emotional stimulus. And as a mixture of thought and of vision provides more stimulus, by suggesting both, both clear thinking and clear statement of particular objects must disappear. The undigested “idea” or philosophy, the idea-emotion, is to be found also in poetic dramas which are conscientious attempts to adapt a true structure, Athenian or Elizabethan, to contemporary feeling. It appears sometimes as the attempt to supply the defect of structure by an internal structure. “But most important of all is the structure of the incidents. For Tragedy is an imitation, not of men, but of an action and of life, and life consists in action, and its end is a mode of action, not a quality.”[6] Footnote 6: _Poetics_, vi. 9.
